Description

The invention relates to a drive system for a partition system, which consists of individual elements, some with drive means are provided for the automatic process, the individual elements on or in a guide rail attached to the ceiling Rollers or other means are horizontally movable in the way that out a lined up arrangement of the individual elements in a jammed parking position can be moved automatically. there has at least some of the individual elements separate drive means, through which the elements in question independently and / or simultaneously be moved along the guide rail by the other elements can. A central control unit with a Microprocessor used, the output signal of at least one Two-wire connection (data bus) to all drive means who makes data and addresses. Technically, it is also possible, besides to use an additional control line for the two-wire connection. There is an individual control and regulation of the individual Elements possible, both in terms of travel speed and with additional ones Functions. In addition to the use of a direct current drive also a control unit can be used, which over existing low-voltage lines the control and regulation of the individual elements. All of them can be operated via a control terminal Program data can be read out and changed.

DE 44 24 660 C1 describes a device and a method for the Operation of an automatic partition system described in which the individual elements horizontally by a common drive be moved. The system is designed so that an existing portable partition system in retrospect also a motor device can be attached, which allows the to move individual elements by motor force. For this type the existing system, which could be operated manually, is not replaced, which means at the same time that another manual movement of the individual sub-elements is possible. For automation is in front of an existing guide rail in which the individual elements the partition system can be moved, another rail system attached in the ceiling area. In this rail system runs a switchable coupling device with an identification system is equipped to the individual elements, which corresponding Indicators include locating and usually pivoting into the Bring parking position. The entire device is driven by an electric motor that drives an endless belt over a pulley. In conjunction with a programmable logic controller the identification system is controlled so that it contains the individual elements recognizes after a successful learning trip and to the desired parking position or individually in the closed position of the partition.

In a previously unpublished Swiss patent application no. 1160/96 (priority application for WO-A-97/42388, published on November 13th, 1997) with the title "Sliding Wall" becomes a sliding wall with motorized Drive described in which the individual sliding wall elements Have means by which the sliding wall element in question is independent from the other sliding wall elements along the guide rail is movable. Each sliding wall element is used as the drive means assigned its own drive unit with an electric motor. The drive axis of the electric motor is again provided with means through which the operative connection with a along the guide rail or approximately parallel to this attack surface or an attack profile move the sliding wall element along the guide rail can be. To the process of the individual sliding wall elements To be able to carry out along the guide rail is a pantograph device available in operative connection with the busbar device stands and is stationary alongside the guide rail arranged busbar device is moved. The Current collector device when moving the sliding wall element switched electrically conductive to control the drive motor cause. To control the partition system in individual areas, is at least one of the two busbars in a plurality of sections isolated from each other, d. H. Taps divided to this individually energized by a power supply. Such a facility is very complex because a large number of Busbars must be laid.

DE 31 50 581 A1 discloses a control method for remote control purposes on low-voltage lines. Signals from one central station to a number of substations and to Low-voltage lines on which an RF signal is modulated. There for postal reasons, signaling is only permitted if if it does not exceed a predetermined transmission power, this turns Modification procedure to achieve a maximum transmission level the length and frequency of the signals and thus limits the Amount of data.

A facility for communication technology for information transfer shows, for example, DE 33 using the preceding method 46 416 A1. In this setup, a transmitter and a Receiver with the low-frequency mains voltage a high-frequency signal superimposed. For this, the sending and receiving stations are each on different outer conductors connected. To secure information transfer from one phase conductor to another are electronic coupling elements in the form of LC resonance elements described. These electronic coupling elements essentially transmit the useful signals without loss. Oppose they represent a lock for the low-frequency mains voltage, so that corresponding Security requirements should not be neglected.

Another method and an arrangement for controlling communication terminals reproduces DE 42 43 504 A1. For this are within a room one or more input units and a display unit arranged. Data is entered at the touch of a button using an input unit transmitted to another local control unit. By choosing appropriate Function keys on the input unit make a selection, which of the connected communication devices ultimately should be controlled.

In addition, so-called remote controls are used in installation technology known for the existing power grid, for example 256 device addresses can have and controlled directly via a keyboard become. This can be done via a clear LCD display Functions are displayed simultaneously. In addition to manual These processes can also be input by using appropriate Program storage run automatically. So it is conceivable that the control, for example, blinds, lighting, etc. automatically switches on and off again. In addition, is a Controller available to monitor the usual processes. Also at Absence can be done via a corresponding electronic unit Information stored on the phone can be called up and activated.

EP 1 085 159 A2 describes a drive system for a partition system. In this partition system with a plurality of individual sliding wall elements is each wall element by means of a Chassis can be moved sideways in a common track. moreover each wall element has its own drive with an electric operated drive motor. The drive is attached to the wall element and engages with the running rail via drive means. In each of the A local control is provided for wall elements, which controls the drive motor controls the respective wall element and with a central Control exchanges information.

The object of the invention is the state of the art to simplify that a simple control type for automatic Partition wall systems is found and one such Plant, especially with several sub-elements, inexpensively manufactured can be .

The object of the invention is solved by claim 1. The Subclaims give a useful further development of the patent claim 1 again.

The partition system consists of several individual elements that each provided with drive means for driving the individual elements are. The elements can be moved in such a way that they over Roll horizontally inside or on a ceiling system can be moved by guide rails. The movability is particularly necessary if the individual elements from their z. B. lined up arrangement, d. H. from the closed front out into a parking position (train station) should be moved automatically. It can be a partial opening or a complete opening of the entire front. In return, the parked elements must also be moved out of the parking position be brought out into the closed front. The single ones Elements can be independently and / or simultaneously in the guide rails be moved. For each separate item, that is individually this element has a corresponding drive unit with an electric motor, preferably a DC motor, on. Show elements that should not be moved separately no drive unit on. The individual electric motor is controlled in each case via a central control unit equipped with a microprocessor is and all individual contained within a wall Controls elements. The output signal from the central control unit via a two-wire arrangement (data bus) to all of them Drive means forwarded at the same time. The output signal includes in addition to data for speed and position, especially data, which is an identification and thus an address of the individual element define. This is how individual control and regulation of the individual elements possible, at the same time additional additional functions, be it z. B. in the elements themselves or z. B. for Control of switches, for moving the elements in various Railway stations can be realized. A change in dates and addresses can be both wireless using a control panel as well as via a cable connection.

Where in the current state of the art each via a control line only one element can be moved, is the invention of Wish realized multiple elements independently from one another Control data bus. For realistic operation of a partition system it is necessary and also an essential requirement that the individual elements are controlled independently of each other can, on the one hand, a quick opening or a partial opening to realize with little effort.

In the Swiss patent application 1160/96, each individual Element to be controlled independently of others with a own circuit. However, it is also possible within one Individual track sections can be switched at relatively high cost embody.

With the central control unit according to the invention, which in addition to a microprocessor also appropriate memory for storing the individual Having programs and addresses, it is possible to be completely independent a large number of sub-elements from one another via a two-wire connection to regulate and control. The division of the system into individual plays electrical circuits no longer matter. To the individual sub-elements identify, they receive a so-called address, which, for. B. consists of a number. This address is used by means of Handheld terminals entered, whereupon the central control unit the individual Recognizes elements accordingly and the desired program controls and regulates accordingly. This is possible independently, no matter where the individual sub-element is located within the guide rail. It is Of course, it is also possible that conventional in such a system operated track sections for certain, not through the operator terminal functions to be influenced can be realized.

For programming a single element, use the operator terminal the corresponding address of the element selected. At the same time, the central control unit checks whether the entered If the address is valid, if not, a corresponding message is sent to the terminal displayed. Next, the appropriate speed, a with which the individual element is to be moved uniform speed, but it can also be a corresponding one the curves (guide rail) and the placement of the individual elements appropriate reduction or increase in driving speed be programmed. The microprocessor within the central The control unit converts the information into the corresponding one Address of the item and the speed around. The Data is transmitted serially via the data bus, but at the same time also feedback from the individual element to the central one Control unit given, on the one hand, to determine where the element is located within the entire system of guide rails for others at what speed it is traveling and whether all the preset Parameters via the software, especially additional functions and thus commands are executed.

To run the data bus, it makes sense to use a two-wire system, e.g. B. in the form of busbars, so as to use the grinder individual elements receive the corresponding data and addresses to be able to. For this is located within the individual element in the Drive unit a decoder, which the individual from the central control unit transmitted data and addresses decoded accordingly and one Memory that is present within the drive unit, this information makes it accessible and stores it in it.

The decoder checks whether the address sent with its set address Address matches. If the address does not match, then this sub-element does not move in any form and ignores it Fall the incoming data, which means that the previously stored values for e.g. B. Get speed and additional functions stay. Only if the correct address from the central control unit is sent, the decoder evaluates this and outputs the corresponding Information to the drive unit. This will then execute the corresponding driving speed or the corresponding Realize special functions.

In addition to the process of the individual sub-elements, it is also possible over the same data bus, i.e. H. the same supply lines, also turnouts z. B. to switch. In such a case, the course is set also electrically connected to the data bus and also with a corresponding one Address, which means that within the switch has a memory and a decoder. The central one Control unit can thus provide appropriate information about the desired one Forward turnout so that this turnout is the appropriate occupies the desired position.

A digital voltage is supplied by the central control unit both extreme values (peak values) are in the plus range and the minus range. The definition is carried out so that the control unit in the Case where it does not provide any information on the data bus, a quiescent level transmits in the minus range of the voltage. If information is sent, the voltage changes from the minus range to the plus range. So it is possible to find the appropriate information for additional To take functions from the negative part of the digital voltage, since this outweighs the positive part. This is it possible that even corresponding gear changes not with driving of the element must be connected. So it can be said that the voltage in this digital system is independent of the driving voltage of the individual element. It is almost at all times a positive mean value of the voltage used to supply the drive motor is used, while the additional functions from the negative Share of digital voltage, d. H. via a one-way rectification become.

The above statements make it clear that the elements, those with a corresponding electric motor within the drive unit are equipped, a customer-oriented shift and making the process of the individual elements simple and inexpensive, can be implemented without changes in the central control unit. This requires a data bus with two connecting lines that Complex wiring beyond this is eliminated. Let also realize, for example, additional functions such. B. blinds, that are inside the element, open or close the locking the element against unintentional opening turn off the z. B. a transparent pane by appropriate Applying voltage (Privalight) make the additional opaque Take control functions, switch the course to individual Bring sub-elements to different train stations so that the train stations not occupying too large a space and also a procedure within certain sections with different speeds allow.

In addition to the above-described type of control of the individual elements A partition system is also the realization and thus the implementation all the above-described functions with a network bus, d. H. on a low-frequency voltage line (two-wire) a corresponding one HF signal modulated, possible. They are in the RF signal corresponding information for the drive units of each Contain elements that then correspond to those contained in their memories Information after it has been decoded, the desired one Carry out movements of the element (s). Here too a terminal can be used, which gives the user the opportunity there to program the corresponding control and regulation functions and then let it run automatically. This is special in view of the corresponding business hours it makes sense to so timed processes by using appropriate program memory to run automatically, e.g. B. Open or close the partition or only a partial opening or partial closure.

The power supply of the entire partition system can either by separate busbars running next to the guide rails be carried out, or it is also possible that within the guide rail the busbars are integrated. In another use case it would also be possible with a corresponding separation the guide rail, the guide rail simultaneously as a busbar acts.

All the data necessary to make such a partition system easy can be controlled via induction, for example on the system, be transmitted. In such a case it could also be done at the same time the supply energy is also transmitted. Beyond that it is also possible that only the data on the data bus via radio or a corresponding infrared transmission are transmitted.

The invention is illustrated schematically using a possible one Embodiment explained in more detail.

In FIG. 1 is a control unit denoted by 1, on which a electrical connection 30 a control terminal 29 is connected, reproduced. The electrical connection can be modified 30 drop and the operator terminal 29 can his data to Control and change the entire system wirelessly to the control unit 1 transferred. The control unit 1 is with a system of busbars 4 connected, only one in FIG. 1 for the sake of simplicity Busbar 4 has been shown. Act with the busbar 4 Current collectors 5, 6, which are also separated directly via electrical connections 12, 13 Wing drive units 14, 23 are connected together. The supply voltage supplied by the control unit 1 is thus via the busbar 4, the pantograph 5 and the electrical connection 12, for example delivered to the wing drive unit 14. The Wing drive unit 14 includes a drive 15 in the form of an electric motor. With a partition system it is not necessary that all elements have a separate drive 15. Rather it is it is also conceivable for individual elements to be mechanically connected to one another are. The drive 15 is connected via an electrical connection 17 the corresponding supply voltage from the wing drive unit 14 supplied. Within the element, for example the Wing drive unit 14 is via an electrical connection 19 an element decoder 16 for decoding the busbar 4, the pantograph 5 and the electrical connection 12 included Data connected. A feedback comes from the element decoder 16 back via an electrical connection 18 to the wing drive unit 14. These data of the decoder 16 are then in opposite directions Direction as the received data to the control unit 1 via the Busbar 4 sent back. On the wing drive unit 14 is in the embodiment, a lock 22 connected. The lock 22 is provided with the corresponding data, also from the Control unit 1 via the busbar 4, the pantograph 5 and the electrical connection 12 has been passed on to the latch 22, controlled. In a similar way, there is also a feedback Carried out via an electrical connection 21 to the control unit 1.

If the partition element connected to the wing drive unit 14, for example in the form of a sliding wing, process and has received a corresponding driving order, as is already the case in described in the general description to understand it so that this Partition element due to its given address to a certain position moves. This can also be done via a switch, for example happen. The switch has a switch drive 2, which over the Busbar 4 and an electrical connection between them 7 communicated by the control unit 1 the corresponding control signal becomes. At the same time there is a turnout decoder in the turnout drive 2 3, which contains a memory and thus the received data can read out from the data bus and an actuation of a point machine 2 causes. One also goes from the turnout decoder 3 electrical connection 8 back to the control unit 1 via the Busbar 4. In the manner described above, a variety Independent of sub-elements of a partition system at the same time regulated both in speed and in their positions and to be controlled. In the exemplary embodiment described above the wing drive unit 14 on the lock 22 with which the entire closed wall then when it is in the closed Position is properly locked. Another wing drive element 23 that via the electrical connection 13 with his Current collector 6 is also connected to the busbar 4, includes a drive 25 which is connected via an electrical connection 24 the wing drive unit 23 is connected. This drive 25 also has an element decoder 26 to which data via an electrical connection 28 can be supplied and at the same time data from the Element decoder 26 read out via a connection 27 and sent back become the control unit 1.

In addition to the control of the point machine 2 described above another number of turnouts within the partition system possible, for example a further point machine 36, which has a electrical connection 9 is connected to the busbar 4. This too Turnout drive 36 has a turnout decoder 10 with a memory on. The feedback from the switch decoder 10 to the control unit 1.

In the exemplary embodiment in FIG. 2, there is an operating terminal 33 which includes a receiver 34 and a transmitter 35. The corresponding signals and data are transmitted via an antenna 38 received to a transmitting and receiving unit 31 with its antenna 37. This transmitting and receiving unit 31 can either in the Control unit 1 may be integrated, but it is also possible that it is adaptive is connected to the control unit 1 and thus via an electrical Connection 32 can be firmly connected to the control unit 1.

In addition to the schematic representation of Figures 1 and 2 is in a 3 shows a partition system, which is equipped with guide rails 45 and 48. These guide rails 45, 48 are connected to one another by a branch 46. In addition, branches 47, 49, 50, 51 present. At branches 47, 49, 50, 51 are located Turnouts with their turnout drives 2, 36, 42. The turnout drives 2, 36, 42 each have a turnout decoder 3, 10, 39. The turnout decoder 3, 10, 39 are connected via electrical connections 54, 55, 56 the busbars 4 running next to the guide rails 4, 48 connected. At the same time there is also one for controlling the last wing further busbar 40 available, which by appropriate electrical Connections 41 is connected to the busbar 4.

The elements of the partition system can now be added to the corresponding ones Parking positions, which in this case are placed in wall niches 44, 45, 58 have been run in. The elements 52, 53 controlled via the point machines 2, 36, 42 so that they are in the parking position, which in the exemplary embodiment is located within a wall 43, can be driven. The control of the point machines 2, 36, 42 happens via the busbars 4, as does the speed control and positioning of the individual elements.
